mkosi: Switch to use mkosi presets with prebuilt initrds Instead of building the initrds for the mkosi images with dracut, let's switch to using mkosi presets to build the initrd with mkosi as well. This commit splits up our single image build into three separate mkosi presets: 1. The "base" preset. This image contains systemd and all its runtime dependencies. The sole purpose of this image is to serve as a base image for the initrd and the final image. It's also responsible for building systemd from source with the build script. The results are installed into the base image. Note that we install the systemd and udev packages into this image as well to prevent package managers from overriding the systemd we built from source with the distro packaged systemd if it's pulled in as a dependency by another package from the initrd or final profiles. 2. The "initrd" preset. This image provides the initrd. It's trivial and does nothing more than packaging the base image up as a zstd compressed initramfs and adds /init and /etc/initrd-release symlinks to the image. 3. The "final" preset. This image builds on top of the base image and adds a kernel and extra packages that are useful for testing and debugging. We also split out the optional kernel build into a separate set of config files that are only included if a kernel to build is actually provided. Note that this commit doesn't really change anything about how mkosi is used. The commands remain the same, except that mkosi will now build all the presets in order. "mkosi summary" will show the summary of all the presets. "mkosi qemu, boot, shell" will always boot the final preset. With "-f", all presets will be built and the final one is booted. "-i" makes a cache of each preset. The only thing to keep in mind is that specifying config via the mkosi CLI will apply to each of the presets. e.g. any extra packages added with "-p" will be installed in both the initrd and the final image. To apply local configuration to a single preset, create a file 00-local.conf in mkosi.presets/<profile>/mkosi.conf.d and put all the preset specific configuration in there.

mkosi: Update to latest This update introduces the explicit Dependencies= setting, instead of relying on implicit dependencies via alphanumerical ordering. We also take the opportunity to rename the "final" preset to the "system" preset, which seems like a better name.

mkosi: Make sure our systemd build always overrides the distros Currently, we install the systemd install tree in the base image and then build the initrd and final images from the base image. This means if that any systemd package is pulled in during the initrd or final image builds, it will override our version. To fix this, we stop installing our build of systemd in the base image, and store it in the output directory instead. That allows us to refer to it using ExtraTrees= in the final and initrd image builds to install it after all the distro packages have been installed, ensuring our version always takes priority.

MakeInitrd=yes
mkosi: Update to latest Configuration now takes priority over CLI options so we have to configure the defaults for settings that we want to allow overriding from the CLI. We also explicitly set some other settings so that they can't be overridden from the CLI anymore. For example the base and initrd image should never be made bootable so we set Bootable=no explicitly for both.
